A gate driving circuit and a display device including the same are disclosed. The gate driving circuit includes a plurality of signal transmitters which are cascade-connected via a carry line to which a carry signal is applied from a previous signal transmitter, and a repair line connected to the plurality of signal transmitters, wherein a signal transmitter includes a circuit part to receive the carry signal from the previous signal transmitter, and charge or discharge a first control node and a second control node, an output part to output a gate signal and a carry signal based on potentials of the first control node and the second control node, and a repair block connected to the repair line and to output a repair gate signal replacing the gate signal and a repair carry signal replacing the carry signal when a logic signal is applied from the repair line.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The gate driving circuit of claim 4, wherein when the logic signal is applied from the repair line, a first output node to which the gate signal output by the output circuit is output is electrically separated from the output circuit and is electrically connected to the first repair circuit, and a second output node to which the carry signal output by the output circuit is output is electrically separated from the output circuit and is electrically connected to the second repair circuit.
7. The gate driving circuit of claim 6, wherein when the logic signal is applied from the repair line, a first output node to which the gate signal output by the output circuit is output is electrically separated from the output circuit and is electrically connected to the repair circuit, and a second output node to which the carry signal output by the output circuit is output is electrically separated from the output circuit and is electrically connected to the repair circuit.
15. The display device of claim 10, wherein all transistors in the data driver, the gate driver, and the sub-pixels are implemented with oxide thin film transistors including an n-channel type oxide semiconductor.
18. The display device of claim 16, wherein all transistors in the data driver, the gate driver, and the sub-pixels are implemented with oxide thin film transistors including an n-channel type oxide semiconductor.
